Inter-language comparison of verbal material for the study of concept formation. — A list of 215 French words, which were translation equivalents of the words in Underwood and Richardson's (1956) published list, were presented to 119 French students from which single, restricted to sense impression associates were obtained. A systematic inter-language comparison is established and differences between French and English speaking subjects discussed. The piocedure adopted by Mednick and Halpern (1962) to study the ease of concept attainment as a function of Associative Rank has been applied to French subjects. A replication using a direct translation of the English nouns shows no difference between concepts at Associative Rank 1 and 2. It appears indeed from norms of the French group that the concepts selected are balanced not only with respect to Dominance Level but also with respect to Mean Associative Rank. But further experiment, with a material established according to the norms of the French list of associates, shows a very significant difference in the mean number of trials taken to solve each concept. It thus strengthened the assumption of homogeneity of associative response hierarchies in a given language community. 相似文献

The four stages preceding the postconventional level in the Kohlberg (1958, 1971, 1976) system of moral development are described as involving moral judgments that conform to external conditions of punishment, reward, social expectation, and conformity to the law. No special level of self-control seems necessary to behave in keeping with these conditions of external reinforcement. In contrast, the two stages of postconventional (principled) mortality involve defiance of majority opinion and defiance of the law--actions that would seem to require greater self-control. This study was concerned with whether postconventional moral reasoning, as measured by the Kohlberg Moral Dilemma Questionnaire (MDQ), can be associated with higher self-control. If so, prediction of principled moral behavior from the MDQ would be based not only on postconventional moral reasoning but bolstered by the necessary level of self-control as well. College students who came the closest to postconventional moral reasoning showed better self-control than college students who were more conventional or preconventional in their moral judgments. These results support the validity of the MDQ for predicting principled moral behavior. 相似文献

The aim of this study was to provide some evidence of reliability and validity of the 15‐item Spanish version of the Utrecht Work Engagement Scale (UWES) between two multi‐occupational samples. In two different studies, 525 human services employees (study 1; males = 233; females = 292) and 409 multi‐occupational employees (study 2; males = 179; females = 230) completed the Spanish UWES. In study 1, our results revealed satisfactory levels of reliability for each subscale. In addition, the confirmatory factor analysis revealed that the three‐factor model fitted better than the one‐factor model and supported the theoretical three‐factor structure (vigor, dedication, and absorption). Furthermore, results from the multi‐sample analysis found strict factorial invariance of the Spanish UWES across gender, suggesting that the UWES factors show the same composition and interpretation in both groups. In study 2, our results once again confirmed the same three‐factor structure for the Spanish UWES. We found support for theoretically proposed two‐factor model including: (1) emotional exhaustion and depersonalization and (2) all three dimensions of engagement plus personal accomplishment. We also found evidence of convergent, discriminant, and incremental validity with respect to burnout, life satisfaction, and perceived stress. In short, our results provide empirical support for structural validity of the Spanish UWES in multi‐occupational workers. 相似文献

Right–left approach and reaching arm movements of 4-month infants in free and constrained conditions
Recent theories on the evolution of language (e.g. Corballis, 2009) emphazise the interest of early manifestations of manual laterality and manual specialization in human infants. In the present study, left- and right-hand movements towards a midline object were observed in 24 infants aged 4 months in a constrained condition, in which the hands were maintained closed, and in a free condition. A left-hand dominance for approach movements without contact with the object, and a right-hand dominance for reaching movements with object contact was observed in the free condition. In the constrained condition reaching movements of the right hand decreased dramatically. These results are interpreted as strong evidence of manual specialization in 4-month olds, with approach movements having a localization role and reaching movements announcing future right-hand dominance for prehension and object manipulation. 相似文献

There has been significant interest in whether and how school climate and violent behavior are meaningfully related. The present meta-analysis reviewed studies reporting a relationship between school climate and school violence in order to summarize the total effect and the direction of these research findings. Database consultation and literature hand searching yielded 145 articles which were reviewed by two experts. Studies were included if they reported a statistical effect size of the relationship between school climate and school violence. Exclusion criteria were unclear operationalization of the principal variables, research findings from multiple publications, studies using multi-level analysis and qualitative studies. The meta-analysis included 36 independent studies (N = 113,778) with correlations ranging from ? .02 to ? .53. Using a random-effects model a moderate mean effect size of r = ? .26, CI [? 30, ? 21] was found. Statistical findings indicated significant heterogeneity and a large range of variance between studies. Meta-regressions analyzed different potential moderators as relevant factors of heterogeneity, but none of these factors could be identified as a moderator. Due to the large variance between the studies, it remains difficult to draw final conclusions. Nevertheless, the moderate effect size underlines the role of environmental aspects for school violence intervention. 相似文献
